5.6.2 Alarm Outputs

There are eight alarms available that provide outputs via Form “C” relay contacts. The last two of these are pre-assigned as the Minor and Major alarm outputs. The Major relay is energized (NO-C contacts closed) during normal (non-alarm) operating conditions; all the other relays energize when an alarm condition occurs. The other six outputs are initially designated as “Relay 1” through “Relay 6” (the user may assign more meaningful names if desired). The various system alarm conditions can be assigned to any of the eight alarm outputs.

Table 5.6-3 shows the alarm output connection designations. Wago Connectors are located on the interface card mounted in the top left side of the unit. The relay contacts should only be used to switch resistive loads of 0.5 amperes or less at 60 volts or less.

5.7 Connecting The Loads

5.7.1 DC Circuit Breakers and Fuses

Both plug-in circuit breakers and GMT fuses can be installed in the MX28B600 power plant for DC distribution circuit protection. Two plug-in circuit breaker tiers, consisting of a 24-position panel (breakers labeled 1 to 24) and two 10-position panels (breakers labeled 25 to 34 and 39 to 48), provide 44 positions of -48V distribution. Available plug-in circuit breakers are shown in table 5.7-1. Plug-in circuit breakers rated at 60A or more require two mounting positions and require a breaker adapter kit, which is included (see kit selection information below the table). The breaker adapter kit includes all necessary mounting hardware.

An optional load shed circuit is available. This option will disconnect any unessential loads from the rest of the system. Loads hooked up to the lower left tier (CB 26-35) will be disconnected. This will preserve the battery run time for essential loads. When hooking up the loads, ensure that they are divided correctly.
